SPECIFICATION forming part of Letters Patent No. 765,747, dated July 26, 1904. Application filed July 3l, 190i). Serial No. 25,472. (No model.)

T0 all 'whom it may concern:

Be it known that I, JOHN H. MoCoEMIoK, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

My invention relates to improvements in detail-adding cash-registers.

My object is to provide a simpler form of cash-register which can be made at a low cost.

Most of the features of my invention are particularly adapted to the type of machine referred to, although some of them may be used in other kinds of cash-registers.

In the accompanying drawings, forming part of this specification, Figure l represents a perspective view of the machine embodying my invention, the cabinet being omitted and the cover for the cash-till being open to eX- pose the till. Fig. 2 represents a vertical section, partly broken away, through the same on the line m .fc of Fig. l, the parts being inclosed in the cabinet. Fig. Brepresents a vertical section through my machine on the line 1/ 1/ of Fig. l, the cabinet being omitted. Fig. 4 represents an enlarged detail side elevation of the keys, key-coupler, rock-shaft, and cooperating' parts. Fig. 5 represents a detail rear elevation of the pivoted hangers or key-stops. Fig. 6 represents an enlarged detail side elevation of the turn-to-zero gearing and its stop. Fig. 7 represents a detail side elevation of the lever for operating the indicator-supporting frame and the devices whereby it receives motion from the rockshaft. Fig. 8 represents an enlarged detail perspective view, partly broken away, of the rock-shaft and its spring and cooperating parts. Fig. 9 represents an enlarged detail perspective view of the key-coupler, lockingplate, coupler latch-lever, and cooperating parts. Fig. l0 represents a detail perspective view of the full-stroke devices for the cabinet-cover, and Fig. ll represents a detail perspective view of the bell-operating levers and operating-cam.

In the aforesaid drawings, 1 represents the inclosing cabinet; 2, the main frame; 3, the cash-till; 4, the movable lid for the same; 5, thc cash-keys, and 6 the indicators. Each of the keys 5, as more clearly shown in Figs. 4 and 9, is hung upon the transverse shaft 9 and comprises, in addition to its shank, upon the upper end of which it carries its designating numbered button, a nearly straight hanger 7, which inclines rearwardly and is provided at its lower end with a rearward extension 8.

As is usual in machines of this kind, each key is provided with an actuating-pawl 10, Fig. 3, which is pivoted to the hanger, while a spring Il, which connects the front end of each pawl with the shank of its respective key, by its tension, keeps the rear or operating end of the pawl in engagement with the ratchet-teeth I3 of its primary adding-wheel I4. The rear end of each pawl is bent laterally to form a flange l2, and it is this ange which engages the ratchet-teeth of the primary adding-wheel.

Many machines of this class which have been heretofore upon the market have been defective in that when a key is operated violently the adding-wheel acquires such momentum at the end of the downward movement of the. key that it would overthrow or turn farther than it should, and thus record a larger amount than the numerical value of the operated key. In my present machine to guard against this overthrow the relative arrangement of the rear edge of each key-hanger 7 and its cooperating flange l2 is such that as the key completes its initial or downward movement such rear edge of the hanger' contacts with the lower edge ofv the iiange 12 of the actuating-pawl and locks it into engagement with the ratchet-teeth of the cooperating primary registering-wheel, and thereby absolutely prevents overthrow.

There is a lower row or series of primary registering-wheels, vertically above which/is 'oted bell-crank lever located the row or series of secondary addingwheels. In the usual manner a pair of adding-wheels cooperates with each keythat 1s,

lwhen a-key is operated it turns its primary adding-wheel one tooth. When the latter has made a complete revolution, its transfer-pin `15 engages a tooth of the ratchet-wheel of the secondary adding wheel and turns it one notch, which construction and operation in a general way are so well known as not to need more specific description here. Each of said pairs of wheels is provided with a pair of retaining-pawls 19 and 20, which are pivoted upon suitable transverse shafts and have a coiled spring which tends to swing the pawls in opposite directions, and thereby holds them in engagement with the ratchet-teeth of their cooperating adding-wheels.

The front of a wheel guard-plate 1, mounted in the cabinet, as shown in Figs. 2 and 3, is formed,as shown in Fig. 1, with two longitudinal reading- slots 22 and 23, through which the proper numbers on the wheels 14 and 17 are exposed to view when the lid 4 of the cabinet, hereinafter described, is raised. The portion of the guard-plate just above the slot 23 is bent rearwardly, as shown in Fig. 3, so as to permit the reading of the lower counter-wheels.

The guard-plate between the slots 22 and 23 is suitably marked to indicate the values of the respective wheels, and in case of the special-transaction Wheels it is marked with characters for indicating what they represent. The special keys 25 cooperate with their special-transaction wheels in substantially the same manner as do the amountkeys with their cooperating adding-wheels. The special wheels are preferably numbered consecutively, so as to keep a record of the number of times each key is operated.

All of the counter-wheels of the upper and lower rows are journaled upon transverse rotary shafts 26 and are arranged to be picked up and returned to zero by said shafts by means of spring-pressed plunger-pawls 27, mounted in suitable yoke-frames 28, fast to said wheels, as shown in Fig. 3. The operating ends of these plungers are arranged to be engaged by the walls of longitudinal grooves 29, formed in said shafts, and thus upon the rotation of said shafts the wheels will be carried therewith and returned to zero. The shafts 26 are simultaneously rotated by intermeshing gears 30 and 31, fast thereto near the righthand ends thereof, as shown in Fig. 6. The gear 31 meshes with a pinion 32, fast to a short shaft 33, journaled in vthe frame, so that its end projects from the side of the machine for the attachment of a milled operating-wheel 34, as shown in Fig. v1. Normally the wheel 31 is locked against rotation by the end of a piv- 35, which coacts with a stud 36, mounted on said wheel.

crank is held down upon a collar 37 on the Vturning to Zero.

The bellwheel 31 and in the path of the stud 36 by a coiled spring 38, interposed between said lever and a portion of the cabinet. The forward end of the bell-crank lever projects through a suitable slot formed in the guard-plate 1 and is provided with a laterally-projecting finger-lug 39. When it is desired to turn the counter-wheels to zero, the cabinet-cover 24, hereinafter described, is first opened, and the lug 39 is drawn forward, thus rocking the bell-crank lever and lifting its inner end out of the path of the pin 36. rEhe wheel 34 is now given a slight forward movement, which causes the pin 36 to pass under the bell-crank lever. The bell-crank may now be'released Without interfering with the operation of When so released, said bellcrank again assumes its normal position in the path of the pin 36, and thus arrests all the gearing, shafts, and wheels when the zero position is reached after a complete revolution. The aforesaid indicators 6 are of the well-known tablet form and are preferably formed integral with their stems or shanks 40, which latter are mounted in suitable apertured guide- plates 41 and 41, fast to the main frame. The lower ends of the Shanks rest upon the rearward extensions 8 of the keys, and these extensions are prevented from slipping sidewise from under said shanks by the guide-plate 41, which extends down the back of the machine and is slotted to receive said extensions, as shown in Fig. 3. The rear ends of said extensions cooperate with pivotcd hangers or stops 43 (see Figs. 3 and 5) to prevent the simultaneous operation of more than one key in the same bank. rlhese hangers are of the Well-known construction shown in the patent to Heady and Patterson, No. 386,401, July 17, 1888, and are of a form well known in the art, with the exception that they are made extremely light and are formed With offset portions 44 near their lower ends to prevent their buckling when the keys are violently operated.

Each indicator-stem 40 provided with a laterally-projecting lug 45 and a. coiled springl 47, surrounding said stem and resting upon said lug. Vhen an indicator is elevated, its spring is compressed against the upper plate 41, and when said indicator is subsequently released the spring assists or starts its initial return movement. rlhe indicators are held in their elevated exposed positions by a supporting-frame 47, mounted fast upon a transverse rock-shaft 48 and provided at its upper edge with a horizontal lip 49.

The rock-shaft 48, as shown morekclearly in Fig. 7, is provided with a rigid pendent operating-arm 50, having an enlarged apertured lower end 51, through'which passes the main rock-shaft 53. A cam 52 on said rockshaft cooperates with a paw] 54, pivoted on said plate to rock said arm 50. The pawl 54 is arranged to move freely in one direction,

IOO

IIO

but is prevented from movement in an opposite direction by a lug 55, formed thereon, a spring 56 holding' said lug in contact with the edge of the arm. The spring 56 also tends to normally draw the arm 50 rearward against a stop-pin 57, mounted on the main frame, and

. thus rock the frame 47 forward to bring the lip 49 into position to support the indicators. The rotary movement which, as presently described, is in'iparted to the shaft 53 causes the cam 52 to engage the pawl 54, and thereby rocks the arm 50 forward, which action rocks the supporting-frame 47L rearward and moves the lip 49 out of the path of the indicator-supporting lugs 45, so as to allow the elevated indicators to drop and the operated indicators to ascend. The eanr 52 linally passes so far around as to clear the pawl 54 when the arm 50 is. drawn back toits original positionby the spring 56, and the supporting-frame 47 is thus rocked forward to bring the flange 49 under the elevated lugs 45 to hold the operated indicators intheir elevated positions. As the cam 52 moves back it simply rocks the pawl 54 on its pivot without moving the arm 50, the spring 56 returning said pawl to its normal position after the cam has passed it. The rotary movement is imparted to the shaft 53 through the medium of two pinions 58, fast to said shaft near the opposite ends of the same, Fig. 8. These pinions mesh with segmental racks 59, formed on the lower ends of arms 60, which latter are loosely hung from the aforesaid shaft 9. The said arms are connected near their lower ends by a key coupling-bar 61, which is pivoted at its ends,

, respectively, to the arms 60 and has a coupling-flange 62. The bar 61 is provided about midway between its ends with a cam-lug 61, Fig. 9, havingits forward end turned upward, so that when said bar is forced rearward by an operated key said upturned end will engage a cam block or projection 61", mounted on an intermediate portion 62h of the main frame, and thus rock the bar 61 downward to bring` the flange 62 in front of a lug 63, formed on the key. This action prevents the return of the key independently of the bar, and thus eli'ects a coupling' of all the operated keys to the bar. As the bar 61 moves forward, however, the lug 61`passes out of contact with the block 61"; but said bai-,then contacts with the hook end of a V-shaped lever 71, hereinafter described, and remains in contact with the same during the remainder of its movementand is thus held positively in its coupling position. Vhen the coupler-bar 61 moves back to normal position, its flange 62 contacts with the rear beveled portions of the noses 63 of the unoperated keys, and said bar is thus forced upward to disengage it from the operated keys. As the shaft 53 is rocked rearward it puts a coiled spring53, Fig. 8, under tension to return said shaft, the coupler, keys, and other parts connectedthereto.to their.

normal positions when the keys have completed their initial or downward strokes. The spring 53 is connected at one end to the main frame and at the other to one of the pinions 58.

A full stroke of the bar 61 in both directions is effected by the fullstroke device illustrated in Fig. 2 and which comprises a toothed segment 64, fast to the main rock-shaft 53, and a pivoted pawl 65, mounted on the main frame. This pawl is normally drawn into the position shown in Fig..2 by a coiled spring 66, which is connected loosely to the shaft 53. This pawl cooperates with the toothed segment to compel a full stroke in either direction in a manner well known in the art and needing no further explanation here.

In order to prevent the operation of the unoperated keys after the movement of any key has commenced and before its completion, I provide a 1)ivotedlocking-plate 67 upon the shaft 53 in such position as to extend .under all of the keys. This plate is provided with a stop-flange 68 along its rear edge, its forward upturned edge being arranged to coperate with noses 69, formed on the respective keys.

Vhen a key is operated, the coupler-bar 61 is correspondingly moved and engages the beveled portion69lL of the hook end 70 of the pivoted V-shaped bell-crank lever 71, which is held in normal position by a light spring 716, Fig. 9. WVhen the bell-crank is thus operated, its lower end, which projects under the plate 67, raises the forward edge of said plate into the paths of the noses 69 of the unoperated keys, and thus locks `said keys againstA operation. Th'e flange 68 normally rests against the under edges of the keys, and thus limits the downward movement of the forward edge of the plate 67. As the key continues its movementthe hook end 70 continues to ride upon the plate 61, and thus holds the plate 67 up to itsv locking position. As the operated key returns, its nose 69 engages the front edge of the plate 67 and positively rocks said plate back to its normal position, the bell-crank lever being meanwhile released by the coupler-bar 61, passing wholly to the front of its hook end 70. The office of the last-mentioned part is to prevent rebound of the coupler.` Should a key be violently returned after being' depressed, its nose 69 will violently engage the front edge of the plate 67, and thus rocking said plate will operate the bell-crank 71 against the tensionof its light spring 7l and cause its hook end to pass over the coupler-bar 61 and. prevent the same from jumping backward.

The money-till 3 is stationary and is suitably divided to provide for the different denominations ofcoins. The cover for said till is mounted upon frames 73, which are pivoted to the main frameat opposite ends of the casing. (See Figs. 2 and 3. )y Each of these frames IOO IIO

-carrying the arm'79 with it.

is provided with a latch-arm 74, notched, as at 75, to receive the lug 76 of one of two latching-arms 77. These arms 77 are fast -upon the opposite ends of a rock-shaft 78, which latter carries an operating-arm 79. (See Fig. 8.) This arm carries a pivoted campawl 80 and is formed with a hook end 81, whichis arranged to cooperate with a pin 82, mounted on one of the arms 60. The pawl 80 is limited in its movements in one'direetion by a lug 83, formed thereon and abutting' against the edge of the lever 79. When the parts are in their normal positions with the tillcover closed, the lugs 76 rest in the notches and are so held by a coiled spring 84, which connects the pawl to the main frame, as shown in Fig. 3. When in this position, the hook end 81 is held out of the path of the pin 82, and the keys are thus free to be operated. When the lid is opened, however, upon the return stroke of an operated key, as described below, the arms 77 are first raised and then allowed' to descend to such an extent that the hook 81 is brought into the path of the pin 82, so that when the arms 60 approach to normal position the pin 82 will first elevate the hook 81 and then pass behind the same to prevent any subsequent operation of the keys until the till-cover is closed and the parts returned to the normal position. (Shown in Fig. 8.

l/Vhen akey is operated as above described, `the arm 60, carrying the pin 82, is moved rearward, rocking the pawl 80 on its pivot during such movement, and thus avoiding any movement of the arm 79. This operation occurs upon the downstroke of the keys. As the keys move back the pin 82 engages the cam edge of the pawl 80, and as said pawl cannot be rocked in a reverse direction because of its stop-lug 83 it is forced upward, This movement of the arm rocks the shaft 7 8, and thus elevates the arms 77 to lift the lugs 76 out'of the notches 75 and release the cover 4. When the cover is released, it is swung downward -by gravity and passes in front of and partly under theforward portion of the till, a suitable free space being left between the till and cabinet for this purpose.

1n order to prevent any shock upon the def `scent of the cover and to bring the same gradually to a stop, I provide each of the frames 73 with a laterally-projecting pin 841. Each of these'pins upon the descent of the cover 4 oontactswith the upper edge of one of two spring-drawn cam-levers 85, pivoted upon the main frame. As the pins 84u pass along the edges of the levers 85 they gradually depress the latter against the tension of springs 85,

which normally tend to draw them upward. The cover is not completely arrested, however,until it has fully opened.

It is very desirable in this class of machines to record the number of times the lid is opened to give access to the turn-to-zero devices and the registering-wheels. To this end the lid 24 is provided with a pivoted link-bar 86,

Awhich is in turn pivotally connected to a bellcranklever 87. This lever is pivotally mounted upon the shaft 9 and carries a spring-drawn actuating-pawl 88, which cooperates with a pair of counter-wheels substantially in the same manner as the pawls of one of the special keys to count one unit at every operation. The lower end of the bell-crank lever is provided with a segmental full-stroke rack 89, carrying two tripping-pins 90, located near its opposite ends. A rigid frame 91, carried by the shafts 26 and 9, forms a support for a double full-stroke pawl 92, which is provided with a trip-arm 93 and an operating-arm 94. The trip-arm is arranged to coperate with the pins to trip the pawl from one of its inclined positions to the other to allow a reverse movement of the parts in a manner well known in the art. The arm 94 carries a pivoted rod 95, which projects loosely through an apertured shoulder 96, formed in the frame 91, and carries a coiled spring 97, which surrounds it and bears against the end of arm 94 and said shoulder. (See Fig. 10.) It will be observed that the tension of this spring will be exerted to hold the arm 94 to either one or the other side of its dead-center, and thus hold the full-stroke pawl to its work in either direction.

As shown in Fig. 1, the counting-wheels of the lid-counter are slightly separated from the remainder of the counter-wheels, so as not to be confused with the same, and are read through apertures 22 and 2311 in the guard 1. The aperture 23a is made in substantially the same manner as the slot 23, before described.

As it is desirable to sound an alarm each time the till-cover is opened, YI provide the bell 98. (Shown in Fig. 3.) This bell is suitably secured to the main frame and is sounded by a clapper 99, mounted on a pivoted bell-crank lever 100, which is journaled upon the shaft 48. This lever is pivotally connected to an angular lever 101, pivoted on the shaft 78, (see Fig. 11,) and is'provided with a pivoted pawl 102, having an angular operating-flange 103 and a stop-lug 104. The pawl and also the lever 101,are held in normal position by a coil-spring 105, which connects the lug 104 to the main frame. (See Fig. 11.) When the shaft 53 is rocked rearward, a camarm 106, mounted rigidly thereon, contacts with the flange 103 and rocks the pawl 102 on its pivot and. finally passes free of the same, the pawl being returned to normal position by the spring 105. Upon the return movement of the cam-armv it again contacts with the flange 103 and forces the lever 101 upward, as the pawl cannot turn upon its pivot in the reverse direction because of the stoplug 104, which engages the side of said lever. The cam-arm gradually elevates the lever 101 IOO IOS

IIO

against the tension of the spring 105 and then finally releases it as said arm passes clear of the flange 103, and thus allows the lever to drop and the bell-clapper to be operated to sound the alarm. The cover 4 is preferably provided near its upper edge with a transverse rib or handle 4, whereby it may be conveniently closed.

It will be seen that by the arrangement of the counting-wheels for the lid-counter upon the same shafts with the regular counterwheels the lid-counter will be returned to zero when the shafts are rotated to return the regular counter-wheels to zero. rI`he lid-counter will thus keep a proper record of the number of times the lid has been opened to read the total of the counter, but will be capable of being returned to zero with the regular counter.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent,`is-
